SPRING WHEEL.

To aZZwhom-itmcg concern:

Be it known that We, 1) YVLADYsnAW Pinnnrnowsni and (2) SrANIsnAw' GRUB- zINsKr, (1) a citizen 0t Polandfand (2) a citizen of the United States of America, residing at Philadelphia, in the county of Philadelphia and State" of Pennsylvania, have invented certain new. and useful Improvements in Spring Vvheels, of which the following is a specification. This invention relates to "certain new. and usetul improvements in spring wheels and has particular reterenceto a spring wheel operating inthe absence of theusual pneumatic tireand adaptedtor use in connection with automobiles or other motor vehicles.

The primary object of the invention residesin theprovisionot aspringcwheel having an* annular rim or band, supporting: a solid cushion tire and enclosing and'spaced from the telly o-t aspoke wheel with metallic springs interposed between the telly and band;

A' further objectof the inventionhas reterence to a spring wheel wherein, metallic coil 1 springs are interposed between" the telly ot the wheel and an enclosing rim member, the v ends ot the springs being secured to said telly and rim for a direct radial mounting, or tor mounting at an incline to the radius of the wheel.

With the above general objects in view the invention consists of the novel combination and arrangement of parts hereinafter more fully described in connection with accompanyin g drawings, and in which like reterence characters designate corresponding parts throughout the several views.

The drawings Figure l is a side elevational view partly broken away of a spring wheel constructed in accordance with the present invention, showing one of the springs extending between the wheel telly and the enclosing rim and the flexible side sheet connected to the telly and rim, I

Referring more in detail to the accompanying drawings, and particularly to F ig- .uresl and Qthere is illustrated a spring wheel having a hub portion 1 carryingradial spokes 2 with a wheel telly 3'carried' bythe outer ends of the spokes. An annular band or rinr encloses the telly 3 and .is'spaced therefrom-by spring devices to be later described, the P1111 4: supporting the solid cushion the 5, flexible s'ide sheets 6' formed of rubber or tabric providing a closure at the opposite sides of the telly 8 and Time, the fleXiblesheet-s Gb'ei-ng secure'd'tothe ri m'and telly by ring members? as clearly shown in Figures-1 a nd2. 5 i

The telly band S'is secured as'at' 9 to the telly S and the V opposed faces of" the 'rim' t and. the band 8, each carry a circumferentially extending rib 10, the opposed faces of said ribs being similarly constructed tor anchoring the opposite ends of the coil springs 11 thereto. The construction of the rib faces is more clearly shown in Figures 5 and 6, the mounting tor each end of the spring including the provision of spaced sets of transversely extending and adjacently positioned grooves 12, and an internally threaded screw receiving socket 13 at each side of the grooves. Coil springs 11 have angularly bent ends 14 that are received in one of the grooves 12 of each rib 10, the spring ends 14 being retained in the grooves by the clamping blocks 15 each having a transverse groove 16 in one of the faces thereotthat receives the spring ends 14:, the opposite faces of the clamping blocks 15 being provided with elongated slots 17 for the reception of screw bolts 18 freely extendin apparent, it being noted that the spring arms 14: may be positioned in either one of the sets of three grooves 12 and rigidl mounted relative to the rim 4: and folly band 8 by the anchoring blocks 15, the screw bolts paxing through the slotted openings 17 in said an choring blocks received in the adjacent threaded sockets 13. The cushion springs 11 may be positioned directly radially of the wheel, or the outer ends thereof may be circumferentially shifted to present the spring arms ll for mounting in the desired grooves 12 as the occasion may require. The flexible side sheets 6 protect the springs from contact with objects and also prevent the collection of dirt or other foreign matter between the felly 3 and the rim.

Vhile there is herein shown and described the preferred embodiment of my invention, it is to be understood that minor changes in the construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention.

Having thus described the invention, what we claim as new is 1. In a spring wheel of the type described, a spoke supported felly, a band secured to the felly, a rim surrounding the felly and spaced therefrom, a solid cushion tire carried by the rim, cushion springs interposed between the felly bandand rim, and adjustable anchoring means for the opposite ends of the springs.

2. In a spring Wheel of the type described,

a spoke supported felly, a band secured to i the felly, a rim surrounding the folly and spaced therefrom, a solid cushion tire carried by the rim, cushion springs interposed between the felly band and rim, opposed ribs carried by the felly band and rim and extending circumferentially of the wheel, and adjustable anchoring means for the oppositeends of the springs carried by said ribs.

3. In a spring wheel of the type described, a spoke supported felly, a band secured to the felly, a rim surrounding the felly and spaced therefrom, a solid cushion tire carried by the rim, cushion springs interposed between the felly band and rim, opposed ribs carried by the fellyband and rim. and extending circumferentially of the wheel, the

faces of said ribs having sets of spaced transband and rim and each carrying at opposite ends an angle arm positioned in anadj acent groove and a clamping block having a groove formed in the inner face thereof receiving the adjacent springangle arm and anchored to the adjacent ri i In testimony whereof we affix our signatures. f
